Lat-Long maps and v.digit

[Eloise Doherty]

Is there a way to register lat-long based maps using v.digit? It says it 
can do it, but every time I've tried, it blows up when I enter the 
registration points? Barring that, is there a good translation program 
for lat-long NAD 1927 to UTM?

Thanks for the help.
